BMW Pro Satnav - How to Upgrade?

[roadsweeper]

I have a 2007 BMW 335d M Sport Saloon (which I believe makes it an E90?) and would like to upgrade the integrated satnav with the latest maps. My current disc is labelled on the front, "Road Map Europe PROFESSIONAL 07-2" and states that it is part number, "T1000-11912."

Can anyone tell me a good source for the latest Europe maps; I assume I just need a new DVD? I've found these guys but am not sure if it's the right thing:

I would like to be able to enter full postcodes as well; is that possible?

Thanks in advance!

Site itself states it's good for "3-series e90, e91, e92, e93 (2006-2008)", so I would expect you're covered.

I used a version of the disc they are peddling on my Mk4 DVD Nav in my e46 a few years ago. It had all traffic (TMC codes), 7 digit post codes (although it was a bit arse to search), night mode (just a colour/menu hack based upon the language setting), Speed Cam notification and an ///M splash screen. In all it was good, but it did reboot randomly at times, but in general it was OK and I'm a heavy user of Sat Nav.

Note that these discs will *not* be genuine BMW parts and they can be found via other means for much less (i.e., nothing) than that site is pounding them out for. Also note that due to this they are frowned upon by some, so it's up to you. Buyer beware.
